NATHANIEL LOMBARD, OF BROOKIJINE, MASSACHUSETTS, ASSIGNOR TO THE N.LOMBARD IMPROVED GOVERNOR COMPANY, OF BOSTON, MASSACHU- SETTS, ACORPORATION OF'MAINE.

GOVERNOR.

srncrrlcarlon forming part of Letters Patent No. 727,652, dated May 12,1903.

Application filed March 1, 1902.

To aZZ whom, it may concern: Be it known that I, NATHANIEL LOMBARD, acitizen of the United States ofAmerica, and a resident of Brookline, inthe county of Norfolk and State of Massachusetts, have invented certainnew and useful Improvements in Governors, of which the following is aspecification.

My invention relates to I governors, and more particularly to those usedin connection with water-wheels and like apparatus.

It has for its principal object the provision of means for supplying aworking pressure to the governor by a movable member which whilecontinuously operating will have no tendency to'exert more than apredetermined force. I In the accompanying drawings,-"Figure 1 is a sideelevation. of one embodiment of myinvention. Fig. 2 is an enlargedbroken trans verse section thereof on the line 2 2 of Fig. 1. Fig. 3 isa similar partial'longitudinal section on the line 3 3 of Fig. 2, andFig. 4 is a sectional detail on the line 44: of Fig. 3. All sections aretaken in the direction indicated by the arrows. 1 7

Similar characters indicate like 7 parts throughout the seve'rahfiguresof the drawmgs.

The numeral 10 designates a shaft by which a gate, valve, or similardevice is to be operated, this shaft being here shown as oscillated inits bearings by a segmental gear 11, secured to it, with which meshes arack 12. This rack is reciprocated by a piston 13, operating in apower-cylinder 14., to either end of which fluid may be'admitted'throughpassages or conduits 15. These passages communicate through a casing 16,in which operates a valve 17, with a main supply pipe or conduit 18.Exhaust from-the cylinder takes place through the passages 15 and a pipe19. The valve is reciprocated to'control admission and exhaust byrevoluble weights 20, driven bysuitable gearing 21 and operating in themanner usual in this class of devices, as will be clearly understoodfrom an inspection of the drawings.

Forming a portion of the supply-conduit is a casing 22, having an inletfor the conduit Serial 110.96.251." (a. model.)

at 23 at the center of one side-an'd a peripheral outlet at 24:. It isprovided'with a cylindrical projection 25opposite thein'let, which ismounted to turn in a bearing 26, formed in'a standard 27. "The bearingis. shown as slitat one side, and the parts may be drawn together tofixthe casing in place 'bya screw 28, passing through a pair of lugs 29 onthe bearing and threaded into one of them. This arrangement of supportenables the casing to be turned at any angle to provide for any desireddirection of the discharge outlet. From the inletopening leads a pipe30, forming a continuation of the conduit 18 and leading to any streamor body of water from which 6 5' a constant supply may be drawnas, forexample, the fiume'orpenstock of the system. Within the conduit is arotatable pressure membercomprising, in the present instance, a disk 31,providedwith curved wings 32, extending frompoints outside the center ofthe disk a portion of the distance across the circumference ofthecasing. The disk is mounted upon'the end of'a shaft 33, suitablyjournaled in bearings in the standard 27 and rotated at thel desiredspeed through a pulley 34., belted to some source of power, as acounter-shaft 35. Outside the pressure member an annularcha'mber 36 ispreferably formed in the casing; An inclined directing-plate 8o 37 may,if desired, be placed across this chamber at one side ofi-the outlet.

At some point in the conduit between the casing and valve, preferably inclose proximity to the latter, is connected a closed pres- 8sure-chamber 38 by a pipe 39. The conduit is thus constantly closed asregards intermediate lateral outlet, being without reliefvalves or thelike.

It will be seen that when the member with- 0 in the casing'iscontinuously rotated in the direction indicated by the arrow in Fig. 2it will draw in fluid through the pipe 30 of the conduit and produceapressure in the casing radially outward in all directions by thecentrifugal force of the rotating fluid, this pressure being capable ofadjustment to the desired point by the speed of rotation employed,causing it to rise in the conduit and exert its force therein. When thevalve 17 is open [00 for admission, this pressure becomes efiectivewithin the cylinder to move the piston in either direction and open orclose the gate. \Vhen the valve is closed, the pressure re mainssubstantially constant, the body of fluid in the casing whirring freelywith the wings and in the outer peripheral chamber, offering littleresistance and necessitating the expenditure of slight force in thedrivin Then the valve is again opened, the pressure is at once availableto perform its work in the cylinder. .If it is necessary to remove thecasing and pressure member to a consider able distance from thegovernor, it may be convenientto provide the chamber 38, in which thefluid will compress the air when the governor-valve is closed, and thenits force of expansion will, on account of its position, be directlyavailable.

Having thus described my invention, I claim- 1. The combination with apower-cylinder, of a conduit for delivering a fluid thereto, a valve inthe conduit for controlling the admission of fluid to the cylinder, anda con.- tinuously-rotatable member within the conduit serving to createa substantially constant pressure therein when the valve is closed andthe supply of fluid cut off from the power-cylinder.

2. The combination with a. power-cylinder, of a conduit for delivering afluid thereto, a valve in the conduit for controlling the admission offluid to the cylinder, a continuously-rotatable member within theconduit serving to create a substantially constant pressure therein whenthe valve is closed and the supply of fluid out off from thepower-cylinder, and a pressure-chamber communicating with the conduitinproximity to the valve.

3. The combination with a power-cylinder and a continuously-rotatablepressure member, of a conduit in which the rotatable member is containedserving to deliver a fluid under pressure to the power-cylinder, saidconduit being constantly closed against lateral discharge between thepower-cylinder and pressure member, and a valve in the conduit forcontrolling the admission of fluid to the cylinder.

4. The combination with a power-cylinder, of a conduit for delivering afluid thereto, a valve in the conduit for controlling the admission offluid to the cylinder, a casing forming a portion of the conduit, arotatable pres sure member in the casing, and a circumferential chamberin the casing outside of the pressure member.

5. The combination with a power-cylinder, of a conduit for delivering afluid thereto, a valve in the conduit for controlling the admission offluid to the cylinder, a casing provided with a peripheral opening andforming a portion of the conduit, a rotatable pressure member inthecasing, and means for rotating the casing whereby the position of itsperipheral opening may be varied.

Signed by me at Boston, Massachusetts, United States of America, this 2lth day of February, 1902.
